摘要
The present invention relates generally to a method of treatment and/or prevention of hypersensitivity including anaphylaxis in patients receiving replacement therapy molecules that elicit an IgE-mediated response by administering an anti-IgE antibody or a binding fragment thereof. Anti-IgE antibodies inhibit IgE-mediated allergic reactions in the mammals and can also lower the risk of an anaphylactic reaction to a replacement therapy molecule. The administration of anti-IgE antibodies over time also downregulates the high-affinity IgE receptor, further decreasing the risk of hypersensitivity and/or anaphylaxis. The anti-IgE antibody binds to circulating or serum IgE and/or membrane form IgE on B-cells, but not to IgE bound to mast cells or basophils, as this may cause crosslinking. This method also reduces the dose and/or frequency of administration of the replacement therapy molecule by reducing or eliminating neutralizing IgE antibodies specific for the replacement therapy molecule.
